Quick answer
For Form 4506-T, keep the facts used to prepare the paperwork, the signed or final copy, the official IRS source used, proof of customer-controlled submission if sent, and any later IRS correspondence.
Source and advice boundary
This page is education-only and not tax, legal, accounting, filing, payment, mailing, faxing, upload, confirmation, or representation advice. IRS.gov and current official instructions control Form 4506-T mechanics.
What to check next
Do not rely on a draft tool as the system of record. Store proof in your own files and involve a professional when facts are uncertain.
Tax Paperwork can help organize public-preview draft context for some narrow workflows, but the user remains responsible for official-source review, professional advice when needed, and customer-controlled submission records.
Common risk
The common mistake is treating a draft, checklist, payment receipt, upload receipt, mailing receipt, or third-party summary as IRS confirmation. Keep records, but verify official channel rules and follow-up through IRS.gov, official correspondence, or qualified professional help.
